If Parker's information is accurate, Vita sold substantially fewer units than its predecessor, the PSP, which shifted 185,000 units during its launch window in 2005 in the UK - a record that still stands today.

In November last year Sony told Eurogamer it would beat PSP's UK launch sales with Vita - subject to supply.

Over 1.2 million Vita consoles have been sold worldwide, according to Sony's internal figures.

PlayStation Vita arrived in North America on 15th February, before European and Australian launches last week.

As of 19th February, 578,812 Vita consoles were sold in Japan.

Vita also previously launched in Hong Kong, Taiwan and South Korea last year, although sales figures for those regions have not been revealed. The majority of the remainder figure - more than 620,000 out of the 1.2 million total - have presumably been sold in the past two weeks.

"PS Vita was designed to deliver the ultimate portable entertainment experience, and we couldn't be more thrilled with the reaction we're seeing from consumers and the pace at which PS Vita is selling," said Sony Computer Entertainment boss Andrew House.
